With the appearance of Volume 3 of our series the review articles them selves can speak for the nature of the series. Our initial aim of charting the field of nuclear physics with some regularity and completeness is, hopefully, beginning to be established. We are greatly indebted to the willing coopera tion of many authors which has kept the series on schedule. By means of the "stream" technique on which our series is based - in which articles emerge from a flow of future articles at the convenience of the authors-the articles appear in this volume without any special coordination of topics. The topics range from the interaction of pions with nuclei to direct reactions in deformed nuclei. There is a great number of additional topics which the series hopes to include. Some of these are indicated by our list of future articles. Some have so far not appeared on our list because the topics have been reviewed re cently in other channels. Much of our series has originated from the sug gestions of our colleagues. We continue to welcome such aid and we continue to need, particularly, more suggestions about experimentalists who might write articles on experimental topics.

"Analytic Insights into Intermediate-Energy Hadron-Nucleus Scattering," by R. D. Amado, presents a review of optical diffraction leading into discussions of elastic scattering, single- and multistep inelastic scattering, spin observables, and directions indicated for further research. "Recent Developments in Quasi-Free Nucleon-Nucleon Scattering," by P. Kitching, W. J. McDonald, Th. A. J. Maris, and C. A. Z. Vascon cellos, opens with a comprehensive review of the theory, going on to detail frontier research advances in spin dependence in (p, 2p) scattering, isospin dependence, and other quasi-free reactions. The final chapter, "Energetic Particle Emission in Nuclear Reactions" by D. H. Baal, explores new findings regarding direct interactions in the nucleus, thermalization and multiple scattering in nucleon emission, light fragment formation, and production of intermediate-mass fragments. A valuable and instructive trio of papers, Volume 15 of Advances in Nuclear Physics will be of interest to nonspecialists as well as specialists in the fields of nuclear physics, high-energy physics, and theoretical physics.

At the peak of the delta resonance, the pion is the most strongly interacting particle we know. It follows that interactions between pions and nuclei at these energies all tend to involve multiple scattering to some degree. Multiple scattering includes different kinds of processes. In its simplest forms, it involves a sequence of interactions with single nucleons that take place as the pion bumbles its way through a nucleus. Much more interesting is the possibility that there are interactions that in some sense directly involve several nucleons at once. If there are such interactions, can we distinguish between them and the simpler, more prosaic forms of multiple scattering Experimental study of pion-nucleus reaction mechanisms has produced intriguing suggestions that truly multi-nucleon interactions do occur. They are the subject of this paper. To develop this subject I will focus on reactions that cannot happen at all without the essential participation of two or more nucleons.
